gunmen-GAP.

. '1 '0 all whom it may concern Be it known that I, O'r'ro J Gizonrrn, a citizen of the United States of America, re-

siding at Detroit, in the'county of Wayne and. State of Michigan, have invented certain new and useful Improvements in Filler- Caps, of which the following is a'specification, reference being had therein to the accompanying drawings.

The invention relates to filler caps for liquid containers, being more particularly means for quickly opening and closing the v filler, and for forming a liquid-tight seal in the closed position.

To this end the invention consists in the novel construction of ,a cap having a yieldable seat, and further. in the peculiar construction, arrangement and combination of parts as hereinafter set forth. r

In the drawings: Figure 1 is across section through the filler and cap in open position. Fig. 2 is a similar view showing the parts in closed position. Fig. 3 is a sectional plan View; F ig. 4 is a front elevation.

' A is the filler neck for a'radiator or bther or rubber, designedto form a liquid-tight joint; but experience has, demonstrated that withsuch devices after they have been in use for a timefthe material becomes permanently compressed and jjthe joint leaky. I have avoided this objection by providing a yieldable cushion within the filler cap not depend- I ent upon the resiliency of the facing material, and which will at all times seal the joint when the cap is closed.

As preferably constructed the yieldable cushion is formed by a plate E fitting within the cap and overlapping the top edge F of the filler neck. This plate E is .provided with a facing G of suitable sealing-matese'riamd. 704,331.

rial-such for instanceias cork-and thefac? ing is secured by a bott-onrplate H limited to clear the flange F, and secured to the plate E by screws I or other securing device. A

' resilient back for the plate G is arranged between the same and the cap B, this being preferably vformed by oppositely extending tongues J struck out from the metal of the plate. Outward movement of the plate is limited by suitable stops on vthe'cap, preferably by turning in the edge of the cap as indicated at K and K, after the plate E with its facing has been inserted. The'turned-in flange K will-clear the flange F of the filler, so that the cork facing will'bear on the latter, while the resilient tongue members J. will hold this facing in sealing-contact.

To lock the cap in closed position a suitable locking device is provided, which, as shown, comprises the links L pivoted to the member A and at their opposite end connected with a cam lever M, which is adapted to engage with the lug D on the cap. This cam lever when turned inthe position shown in Fig. 2 will depress the cap while the resilient tongues J will yield to permit the corresponding yielding of the plate E and facing G. Thus without regard to the wear or compression of the facing material the cap will at all times be maintained liquid tight.

What I-claim as my invention is:

-1. The combination with a hollow cap member of a liner plate therefor having a resilient tongue struck out therefrom and bearing against the inner face of said cap, and a sealing facing secured to'said plate.

2. The combination with a filler of a hollow cap hinged at one side-to said filler, a

locking lug upon the opposite side of said cap, a yieldab e liner plate within said hol- Specification of Letters latent. Patnted Feb, 17, 1914,

low cap having resilient means bearingagainst the inner face of said cap, and locking means adapted to engage said lug to depress the cap over said filler.

8. The combination with a filler of a hollow cap member hinged at one s ide to said filler, a 'locking'lug positioned upon the opposite side of said cap, a lining member within said hollow cap member, provided with a facing r adapted to bear against the upper edge of said filler, an inturned flange upon said cap for'retainingsaid lining member and cle'ar- In testimony whereof I affix my signature ing the edge of said filler, a resilient member in presence of two witnesse for yieldably pressing said liningmember against said retaining flange, and locking O 5 means adapted, to engage said lug to depress Witnesses; Y 4
